01 — Speakers

The part you actually hear.

Factory speakers are built to a price, not a standard — thin paper cones, weak magnets and no real tweeter, running out of detail the moment you turn it up. A proper speaker upgrade is the single biggest jump in sound quality you can make, fitted to suit how you listen and crossed over so the highs, mids and bass each land where they should.

01

Component Sets

Separate tweeters and mids for a wide, lifelike soundstage up on the dash where it belongs.

02

Coaxials

Clean, simple drop-in upgrades that lift clarity and volume without major fabrication.

03

Crossovers & Placement

Proper crossover and tweeter placement so vocals sit centre-stage, not down by your knees.

04

Sealed & Deadened

Sealed-in baffles and deadened doors so the energy goes into the cabin, not into rattling panels.

03 — Amplifiers & DSP

The power & the polish.

Your head unit's built-in power is the first thing to give up when you turn it up. A proper amp gives speakers and subs clean, controlled power — then DSP makes the whole system sing.

01

Clean, Rated Power

Amplifiers matched to your speakers and subs so they play loud without strain, clipping or distortion.

02

Multi-channel & Mono

From a tidy 4-channel for your doors to a mono block for the sub — the right configuration for your build.

03

DSP Tuning

Digital signal processing sets levels, crossovers and time alignment — the difference between loud and genuinely good.

04

Solid, Safe Wiring

Correct gauge, fused power, upgraded grounds and Big-3 where needed — so the system is reliable, not a fire risk.

Common questions

Speakers, subs & amps — FAQ.

What people ask most before upgrading the sound in their car.

What's the best first upgrade for car sound?+
A proper front speaker upgrade. It's the single biggest jump in clarity and detail you can make, and it works with your factory radio. From there, an amp and a sub take it to the next level.
What's the difference between component and coaxial speakers?+
Coaxials have the tweeter built into the main speaker — a clean, simple upgrade. Components split the tweeter out so it can be mounted higher up, which lifts vocals onto the dash and gives a far wider, more lifelike soundstage.
Do I really need an amplifier?+
If you want clean volume, yes. A head unit's built-in power distorts as you turn it up, which sounds bad and can damage speakers. A properly-rated amp gives clean, controlled power with headroom to spare.
Sealed or ported sub — which should I get?+
Sealed is tight, accurate and musical; great for rock, jazz and all-rounders. Ported is louder and deeper for the same power; ideal for hip-hop, dance and anyone who wants to feel the bass. We'll match the enclosure to your music and your boot.
What is DSP tuning and is it worth it?+
DSP (digital signal processing) sets levels, crossovers and time alignment by ear and measurement so every seat sounds right. It's one of the biggest improvements you can make to a system's clarity and staging — the difference between loud and genuinely good.
Will adding all this drain my battery or strain the car?+
Not when it's wired correctly. We use the right cable gauge, proper fusing, upgraded grounds and Big-3 upgrades where needed, so the system runs reliably without putting your electrics at risk.
Are you a Rockford Fosgate dealer?+
